,To all wij/0771, it mctyconcern: f

Beit known that I, NORMAN N. HAzELToN,

of Lamoni, in the county of Decatur and State i of Iowa, have invented a new and useful Improver'nent in Combined Thresholds and Teather-Strips for Doors, of which the followingis a speciiication.

My invention is an improvement indoors, and especially in the threshold and weather strip constructions; and the invention consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings,

Figure l is a perspective view of a part of a door and frame, the door being open, parts being broken away and oth-V ers shown in section. Fig. 2 is a plan view, partly broken away, of the threshold, the door being shown in section. Figs. 3 and 4 are vertical sections. Fig. 5 is a detail perspective view of one end of the threshold, the top plate being removed; and Fig. 6 is a detail view ot the front of the tripping-bar.

By my construction I provide a combined weather-strip and threshold, the weather-strip being formed in two sections-an upper one A, attached to the door, and alower one B, forming a part of the threshold when the door is open. The upper part A may be of galvanized sheetiron or other'suitable material, and has an upper tiange a, arched slightly, so that when rested against the door it will Aform a spring-arch, which will allow the screws to draw it tightly against the door, making a water-tight joint. From the iiange ct the doorsection A inclines downward and outward at ct',- and has at its lower edge a depending tiange a2, which stiffens the upper section and fits over the lower section when in operation. The lower section B is hinged at b and has at its inner edge an upturned portion or bead b', forming a bearing for engagement by the actuating-piece, and also tending, by bearing against the inner side of the upper section when the door is closed, to form a tighter joint to keep out wind, water, dust, dac. To lift this section B as the door is closed I provide on the door C, Within the upper section A, an,

actuating device consisting of a lifting or tripping bar D, pivoted at d to the door, having a point d to engage the section B when thrown down to operative position, and engaging a stop cl2, by which the bar is stopped in such operative position. In connection with this' tripping-bar I provide means by which it maybe thrown into and out of position to engage the lower section, and also a simple construction co-operating with the said operating means to lock the tripping-bar in or out of position to engage the'lower hinged section B.

To this end I providea handle-rodE, connected at e with the bar D, so that the longitudinal movement of the rod E will throw the bar D into its several adjustments. rIfhis rod E, like the bar D, is incased within the upper section A of the weather-strip, and has at its free end an angular portion e', which may engage be' tween hook-like seats F F on the dooror over the outer seat F', being in the latter adjustment locked to secure the tripping-bar in position to engage the hinged section and in the former adjustment locked to secure the bar out of such adjustment.

On the sides of the door-frame bearing on ends of the threshold are provided the cleats G, having the edges gformed to coincide with and arranged to be abutted by the section A of the 'weather-strip when the door is closed, such cleats overlapping the ends of the section A and guarding the ends thereof, as will.

be seen from the drawings. v

The section B forms a part of the threshold when lowered, and when in such position rests on rubber cushions I-I in the frame I of the threshold, such frame I being formed of wood, cast metal, or, if preferred,of other material, and is cored out, forminga cavity closed at the front by the section B, and the balance of cavity is closed by the removable plate J, which may be easily lifted to clean the threshold-frame ot' dust or other accumulations, and when in place forms a fiush top for the inner portion of the threshold.

In the Vtop of the frame I, near its ends, I form recesses t', communicating with channels i, leading forward under the ends of the section B and opening at the front of the threshold, forming an outlet for such water as may under any circumstances get upon the threshold-as, for instance, when the door is temporarily opened.

Manifestly the dimensions of the several parts may be made to meet the sizes of the IOO doors with which the improvement is to be used.

The frame I is provided beneath the middle of the removable plate J with a portion K to properly support the latter. At each end of the threshold are provided flanges K for the purpose of fitting doors that may not be of exactly the same width as the length of the threshold, the door-jambs being grooved or out out deep or shallow, as seems to be necessary, to receive such flanges. ln 'case the threshold is a little short wedges or other keys may be driven between the ends of the threshold and the jamb under fianges.

It should-be understood that the lifting-bar D is ot' spring metal, having its pointd so deiiected that it will properly engage and lift the section B, and will, as the door closes, operate by its tension to press the section B so tightly against the section A as to -form practically a water and wind tight joint, and the point d of the said lifter D is a hard point riveted on straddle, so that it may wear equally well with section B as they come in contact with each other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the door the threshold having a hinged section the door having a section fitting over the hinged section and the lifter engaging the hinged section made of spring material and arranged to be deflected by pressure against the hinged section when the door is closed whereby the lifter will be thrown under tension and will by its tension press and hold the hinged section tightly against the other section substantially as set forth.

2. The combination of the door, the threshold having the weather strip section hinged at one edge to the threshold frame and provided at its free edge with an upwardly projected rib or bead, the door section fitting over the hinged section, the lifting bar formed of spring metal deflected substantially as described and arranged to be sprung out of normal position and putin tension when the door is closed whereby to spring press the beaded `edge of the hinged section against the door d section, the operating rod connected at one end with said lifter and having at its free end a projecting arm and separate hook like seats arranged for engagement by said arm wherebythe rod and lifter may be positively locked in either of their positions substantially as set forth.
